Screws are an indispensable basic component in the field of assembly machines. They are widely used, ranging from small microelectronic components to heavy machinery and equipment. Different types and types of screws are used to fasten parts. In my country's assembly industry, the use of screw locking assembly has always been a link with a relatively low degree of automation, because currently the industry generally uses vibrating plates or other mechanisms to screen and sort screws, and it is easy to generate The phenomenon of material jam prevents the supply screw from being very smooth.

At present, the drum of the existing drum-type nail feeding mechanism is placed horizontally. When the drum rotates, one end of the drum will rub against the hopper, because there is a certain gap between the two to keep the drum rotating smoothly, but the debris in the drum , material chips, and material slag will enter this gap, and long-term friction will cause wear and damage to the drum and hopper, and eventually cause failure.
